EM1402EVM: Active balancing demo problem

Part Number: EM1402EVM
Other Parts Discussed in Thread: TMS570LS3137, HALCOGEN

Hi,

i am doing active cell balancing in TMS570LS3137. the example code available is working on the evaluation board with SPI communication. now, i want to implement it through MIBSPI not with SPI. 

while debugging, the code getting struck in the following:

g_ui32EMB1428Status = spiTransferByte(mibspiREG1, (EMB_COMMAND<<4));


 if((g_ui32EMB1428Status &(0xF0)) != 0xA0)//done =high, enable=low
   {
   while (1);
   }

and  g_ui32EMB1428Status value is 0xD8. 

i am attaching my halcogen file with code. kindly review it and please let me know if any configuration setting, i am doing wrong.

Thanks in advance,

Regards,

    Hi Gargi,

    We are in the process of NRND this solution, so we are not able to provide further support on deviations from the example code - especially in a format (MIBSPI) that we are unfamiliar with currently for this interface. I apologize for the inconvenience, but perhaps the TMS570 team forum may be able to provide further insight on this.

    Best Regards,

    Taylor
